a Guided Introduction to Elixir - Part 2 of 6
summary
Covers concrete Elixir mechanics: pattern matching with = and ^ and tuple return dispatch, function clauses by arity and anonymous multi-clause functions, recursion reimplementing reduce with cons/destructuring and guard clauses, and macros manipulating the AST. Shows tooling and libraries: Erlang interop, Dialyzer (not demoed fully), IO.inspect, Phoenix examples, REPL/Emacs workflow and a live fizzbuzz exercise. Live coding sometimes produces infinite loops and broken examples so expect working demos interleaved with debugging.
